' Application led February 7, 1916. Serial No. 76,684.

To all whom it may concern Be it known Athat I, LAWRENCE M. PINCE- NEY,a citizen of the United States, residing at Charleston, in the county ofCharleston and State of South Carolina, have invented certain new anduseful Improvements in Razor-Blade Sharpeners; and I' do hereby declarethe following to be a full, clear, and exact description of tieinvention, such as will enable others Skill ed in the art to which itappertains to make and use the same.

The present invention relates to improvements in rai/.or bladeSharpeners in which rotating stroppers are provided to engage withopposite sides of each cutting edge of double-edgedsafety razor blades.

It is an object of the present invention to provide an improved razorblade Sharpener which will be of simple construction, economical ofmanufacture, easily operated, and constructed for convenient and quickinsertion and removal of the razor blades 'between the rotatingstroppers, which are y proved razor blade Sharpener constructed inaccordancerwith the present invention and illustrated with the coverraised. Fig. 2 is a top plan view of the improved device with the coverremoved. Fig. 3 is a transverse sectional View taken on the line 3--3rofFig. 2 and with the cover in place. Fig. 4 is a longitudinal sectionalview taken on the line 4 4 of Fig. 2 and with the cover in position.Fig. 5 is a longitudinal sectional view through one of the rollers orstroppers; and Fig. 6 is a perspective View on a reduced scale ofthecasing with the cover removed and before the stroppers have been mountedtherein.

Referring more particularly tc the drawings, l designates a casing and acover therefor disconnected from the casing and Speccation of LettersPatent.

removable therefrom'. I The casing lis pro? .vided with angle posts 3,fitted in the `corners thereof, as indicated plainly -in Figs. 2

and 6; such posts extending to a height 11py -i wardly therefromsubstantially equal'fto the depth of the cover 2, which latter receivesand is guided by the same when moving position to inclos'e the casing 1.

Along the longitudinal center of the casing 1 is arranged a series ofpins 4-recessed and threaded at their bases to receive screws 5 fittedthrough Ixcountersunk perforatinns in j the base of thecasing l, andwhereby the pins 4 are removably mounted therein. These pins may be in`any number and are adapted to receive the perforations formed in razorblades, such as shown at 6 in Fig. 2, of the Gillette and other types;and the razor blade 6 is slidable vertically on said pins 4, beingunsupported centrally and having the lower faces of its opposite cuttingedges freely resting upon the leather or other abrading surfaces 7 ofwooden or` other rollers, or rotating stroppers 8 and 9. See moreparticularly Fig. 5). These rollers or rotating stroppers 8 and 9 aredisposed in' the casing l to either side of the 'series ofv pins 4, theybeing mounted on square or other shafts 10 and 11 formed, as

c disclosed to advantage in Fig. 5, with round journals 12 and 13,which. may be fitted in pairs of bearings 14 and 15 or directly in theend walls of the casing l, as may be deemed better'in practice.Coperating withA .the rollers or rotating stroppers 8 and 9 of thecasing 1, are a similar pair ofstroppers 16 and 17 havingleather orother suitable abrading faces 18 and 19, and being supported to freelyrevolve in the cover 2 on square or other shafts 20 and 21 formed withround journals litted in spring brackets 22 and 28 extending across theends ofthe cover 2 and being offset centrally, as may be seen in Fig.

4; they having their ends bent inwardly and perforated, as at 24 and 25in Fig. 1, to receive fastening means. It will be understood that thestroppers l16 and 17 may. be readily engaged and disengaged with thebearing brackets 22 and 23 by pressing the same inwardly against therespective end Walls of the cover 2.

The several rollers or -rotating stroppers 10, 11, and 16, 17, areconnected to be driven seid casing, a, cover sldable on said guideposts, complemental pairs` of 4stroppers in lsaid casing and cover forsupporting a razor blade tllerebetween, gear wheels connecting saidelements for simultaneous operat1on,'p1ns 1n sald caslng. for centerlnga razor blade thereln, a crank handle on the exterior of said casing,and gear 4connections between said crank handle and thefstroppers insaid easing, substantially as described.

In testimony whereof, I ax my signature.
